<p>If you’d like to use an ASGI server you will need to utilise WSGI to
|

ASGI middleware. The asgiref
|
||
<a class="reference external" href="https://github.com/django/asgiref#wsgi-to-asgi-adapter">WsgiToAsgi</a>
|
||
adapter is recommended as it integrates with the event loop used for
|
||
Flask’s <a class="reference internal" href="../../async-await/#async-await"><span class="std std-ref">Using async and await</span></a> support. You can use the adapter by
|

wrapping the Flask app,</p>
